Abstract
A casing centralizer which has an annular body having a substantially cylindrical bore extending longitudinally therethrough. The annular body is divided along its axis into two inter-connectable sections, each of which includes fins extending radially therefrom. Each inter-connectable section also includes at least one latch and at least one alignment guide, as well as at least one latch cavity configured for matingly receiving and interlocking with the at least one latch of the other inter-connectable section, and at least one alignment guide cavity configured for matingly receiving and interlocking with the at least one alignment guide of the opposing inter-connectable section. The two inter-connectable sections may then be clamped about a drill pipe for maintaining a centralized position of the drill pipe in a downhole casing.
